The list of musical acts who have chosen to dodge the digital music revolution entirely seems to shrink with every passing year, and this week finds another one scratched off the list for fans of 1970s rock and roll.

Arkham Asylum drops players into the role of the Caped Crusader, who—after a busy night of doling out vigilante justice—has managed to capture and transport the Joker to Arkham Asylum, Gotham City’s island-bound sanitarium and prison for the criminally insane. Despite the hero’s presence, the Clown Prince of Crime breaks free of custody; and instead of escaping (as a sane person might), he opts to lock himself in, take over the institution, and free all the convicts.

In Batman Arkham City Lockdown, players take up the mantle of the Caped Crusader, and are called upon to punch, stomp, and batarang their way through multiple levels populated by a respectable range of low-level henchman and well-known villains plucked from the pages of the DC Universe.
